My invention relates to liquid dispensing apparatus, particularly adaptable for dispensing gasoline, of the type wherein an extra loop of the dispensing hose is normally retracted and stored within the casing of the apparatus. In gasoline pumps of this type the dispensing hose is of such length that approximately or ll feet of hose extends outside of the casing and is formed into a loop when the dispensing nozzle is positioned in the nozzle boot near the top of the casing.

In servicing as high as 95% of the automobiles which stop beside the pump for gasoline, a station attendant is able to reach the gasoline tank of the automobile with the length of hose which always extends outside of the casing. However; occasionally an automobile will stop at the service station in such a position with respect tothe pump that the gasoline tank of the car cannot be reached by the operator with the length of hose which normally extends beyond the casing. In such event, the operator pulls out a sufilcient length of the looped portion ofthe hose within the pump, to enable him to dispense gasoline from the nozzle at the end of the hose into the gasoline tank.

Two obvious and well known means for storing hose within the casing have been adapted forV use in gasoline pumps. Such means are a hose reel on which the extra hose is wound and the arranging of an extra length of hose in a loop within the casing with weight means in the form of a sheave suspended in the bight of such extra loop ofhose. In devices of the prior art, the extra 100p of hose and the sheave in the' bight thereof have been arranged in a well formed within the casing which forms a sort of guide for the hose. In commercial use such structures have proven to be undesi'rable because it is an inherent characteristic of hose used for gasoline pumps that the hose tends to assume a definite position within the well, which results in the hose rubbing against the side walls of the well. Such contact by the hose with the side walls of the well or housing not only materially increases the amount of effort which the operator must exert to withdraw the hose from the casing, but also detrimentally efi'ects the hose covering,

The principal feature of my invention is the mountlng of the sheave, carried in the bight of the extra loop 'of hose within the casing, on a supporting frame provided with a series of guide rollers, preferably grooved, and the utilization of a pair of the angle bar supporting members of the housing as tracks for the guide rollers to insure an easy up-and-down movement of the sheave in a predetermined path of travel.

My invention includes the various novel features of construction and arrangement hereinafter more definitely specifled.

^ Fig'. I is an elevation, partly in section, of the front of a commercial type of liquid dispensing apparatus embodying my invention.

Fig. II is a partly sectional side elevation, on a larger scale than Fig. I, of a part of the apparatus shown 'in Fig. I and showing the Chassis frame angle bar members in guiding relation with the rollers of the supporting pulley frame member.

Fig'. III is a fragmentary sectional view, taken on the lines III, III in Fi'g. II, but on a different scale, showing the arrangement of the angle bar supports in guiding relation to the rollers of the pulley supporting frame member.

Referring more particularly to Fig. I, the pump or curbstand, generally indicated by the reference mark l, includes the rectangular shaped base member 2 on which is rigidly mounted in rectangular arrangement a series of four vertical angle bar chas'sis frame supports 3. Said angle bars 3 are provided at their lower ends with flanges 4 and4 are rigidly mounted on said base member 2 by means of a series of bolts 5 which extend through said flanges ll into screw threaded engagement with said base member 2. Said series of angle bars 3 form a frame support for the sheet metal housing 'I which is also rigidly Asecured to said base 2, by the bolts 5 extending through the fianged bottom end 8 of said housing 1.

The apparatus shown in Fig. I is of the type disclosed in my copending application Serial No. 302,524 filed November 2, 1939, for improvement in Liquid dispensing apparatus, and includes a bridge -frame member lfl, of inverted U-shape, which is rigidly mounted on the base member 2 conveniently by a series of bolts Il. The unitary casing |2 is rigidly mounted upon the top of they bridge frame member Ill and contains the pumping unit and the several valves leading to and from the same, and means for separating the llghter fiuids from the gasoline and separately discharging them as hereinafter described. Said unitary casing |2 is provided with the head cover f' l 5 on which is rigidly mounted the fiow meter IG.

The fiow meter |6 shown is of the type including pistons mounted for reciprocation in cyl- .inders and operatively connected with the meter crank shaft l'l which is provided with the coupling IB at the top thereof for flexible connection with the drive shaft of computing and registering mechanism or other indicating means 20.

Said bridge frame member IB has rigidly mounted within it the electrical motor 2| provided with the pulley 22 which, by means of the belt 23, is in driving relation with the pulley 24 rigidly mounted on the drive shaft 25 of the pumping unit contained within the unitary housing 2.

The liquid supply pipe 2,1 leads from an underground supply not shown, to said n with-which it u conveniently connected by through the meter il and the lighter fiuids being permitted to flow to 'the atmosphere through the vent pipe 33. Liquid passes from said meter |3 through the meter discharge outlet 3| into the discharge conduit 33, see-gage'34, and conduit 33 to which is rigidly connected the flexible dispensing hose 33, conveniently by means of the coupling member 31. Said hose 33 is provided at its distal end' with the dispesing nozzle 33 having a valve normally spring pressed to closed position, but adapted to be openedby manual operation of the nozzle lever 43. i'

As best shown in Figs. II and III, a portion of the flexible dispensing hose 33 is arranged within the casing in a loop 42 which has suspended in the bight thereof the sheave 43 provided with the circumferential groove 44 with which the dispensing hose is engaged. Said sheave 43 is mounted with freedom of turning movement on the stud shaft 43 which is rigidiy mounted, con-4 guide rollers 5| each having preferably a circumferential groove 32 forming flanges. 33 and 34 which embrace the inner edges of the angle bar chassis frame supporting members 3. Each of said guide rollers 3| is mounted for freedom' of tuming movement on a stud shaft 33 which is rigidly mounted on said member 41, conveniently by riveting over the end of said stud shaft, as shown at .51. Said guide rollers 3| are prevented from displacement axially on their respective shafts 56 by means of the pin 33. It is obvious that, if desired, said guide rollers may be formed of separate'pieces instead of a unitary structure.

As best shown in Figs. II and III, Ialso find it desirable to provide said member 41 with a pair of guide. rollers 33 which are mounted for freedom of tuming movement on stud shafts 3| which are respectively rigidly mounted at the two upper comers of the member 41 by riveting over the ends of said shafts 6|, as at 62. Said rollers are prevented from axial displacement on their shafts 3| by means of the washers 83 and pins 34.

As best shown in Fig. I, the dispensing hose 33 extends upwardly from around the sheave 43 to the arcuate guide member 10, which is positioned above the computing unit 23 and rigidly fastened at its opposite ends to the angle bar members 3. Said arcuate guide member 13 carries a series of rollers 1| which are conveniently mounted with freedom of tuming movement on stud shafts 12 rigidly fastened tosaid guide member 10. Where the dispensing hose passes through the housing 1, I provide a roller cage llcomprising a plurality 'of rollers 18, the axes of 'some of which are at right angles to others. Said rollers 13 are so arranged. to assure that the hose is curved through a sweeping radius and not through a sharp short bend when the hose is drawn out of a,s4s,ses w w v by the operator in planes substanwyl/m* M2103 tO m.

A suflicient length of the hose 33, approximately iii or 11 feet, continually extends from the 'opening of the roiler cage 13, which amount of hose is sufiicient to enable the operator to effect normal servicing operations. apparatus I is not being used to dispense fluid to an automo'bile, the hose nomle 33 is positioned withits outer end within a nozzle boot formed.

the supporting member 41 carrying the sheave 43. Similar stops 33 may also be provided at their upper portions of the angle bars 3 to limit the extent of upward travel of the supporting Operation Under ordinary circumstances, an automobile will stop in such close proximity to the apparatus I that the station attendant, after removing the nozzle 38 from the nozzle Jioot, will be able to reach the filling opening of the tank of the autol mobile by utilizing the amount of the hose 3.3 which normally extends beyond the casing. However, the stationattendant occasionally will desire to dispense fluid from the pump to the gasoline tank of an automobile which has stopped at such a distance from the pump I that the operator cannot reach the i'illing opening of the tank of the car with the length of hose which normally extends beyond the casing. In such event. the operator, while holding the nozzle in one hand, pulls on the hose at some point where it extends beyond the casing to withdraw a sufficient amount of the stored hose to enable him to reach the flll cap of the automobile gasoline tank withthe nozzle 33. Such pulling motion on the hose causes the sheave 43 to rotate about its stud 43 and moves the member 41 upwardly i'n' Fig. II, thereby causing the rollers 5| to rotate on their respective studs 53 and roll along the edgel of the angle bar frame members 3. Such rolling When the operator completes his dispensing of fluid to the tank of the automobile, he merely needs to release his hold on the hose and the weight of the sheave 43 and supporting member 41 causes the hose to be retracted into the cas-l ing and to assume its stored position, as shown in Fig. I.

Therefore, I do not desire to limit myself to the precise details of construction and arrangement herein set forth. as it is obvious that various modiflcations may be made therein without de.- parting from the essential features of my invention, as defined in the appended claims.
